# 进入容器内部 docker exec -it elasticsearch /bin/bash # 在线下载并安装 ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip #退出 exit #重启容器 docker restart elasticsearch
安装插件需要知道elasticsearch的plugins目录位置,而我们用了数据卷挂载,因此需要查看elasticsearch的数据卷目录,通过下面命令查看:
docker volume inspect es-plugins
显示结果:
[ { "CreatedAt": "2022-05-06T10:06:34+08:00", "Driver": "local", "Labels": null, "Mountpoint": "/var/lib/docker/volumes/es-plugins/_data", "Name": "es-plugins", "Options": null, "Scope": "local" } ]
说明plugins目录被挂载到了:/var/lib/docker/volumes/es-plugins/_data
这个目录中。
下面我们需要把课前资料中的ik分词器解压缩,重命名为ik
链接:https://pan.baidu.com/s/1KLi71wyX4Znq7GE0jCRUUg?pwd=a3km
提取码:a3km
也就是/var/lib/docker/volumes/es-plugins/_data
:
把解压的文件拉到数据卷中:
# 4、重启容器 docker restart es
# 查看es日志 docker logs -f es
IK分词器包含两种模式:
ik_smart
:最少切分
ik_max_word
:最细切分
GET /_analyze
{
"analyzer": "ik_max_word",
"text": "北京欢迎你我家大门常打开"
}
结果:
{
"tokens" : [
{
"token" : "北京",
"start_offset" : 0,
"end_offset" : 2,
"type" : "CN_WORD",
"position" : 0
},
{
"token" : "欢迎",
"start_offset" : 2,
"end_offset" : 4,
"type" : "CN_WORD",
"position" : 1
},
{
"token" : "你我",
"start_offset" : 4,
"end_offset" : 6,
"type" : "CN_WORD",
"position" : 2
},
{
"token" : "我家",
"start_offset" : 5,
"end_offset" : 7,
"type" : "CN_WORD",
"position" : 3
},
{
"token" : "大门",
"start_offset" : 7,
"end_offset" : 9,
"type" : "CN_WORD",
"position" : 4
},
{
"token" : "常打",
"start_offset" : 9,
"end_offset" : 11,
"type" : "CN_WORD",
"position" : 5
},
{
"token" : "打开",
"start_offset" : 10,
"end_offset" : 12,
"type" : "CN_WORD",
"position" : 6
}
]
}
1)打开IK分词器config目录:
2)在IKAnalyzer.cfg.xml配置文件内容添加并创建文件:
3)重启elasticsearch
docker restart es
完事
